A new tweak called Sireet has become available in Cydia that allows iPhone 4S users to tweet on their Twitter accounts through Siri. Apple has not integrated this service in Siri yet, so if you want this functionality then you should try this tweak out. It works as it should and sends Twitter updates to the twitter account you have set up on your device. As it works with Siri, you don’t have to worry about the speech-to-text conversion mistakes your device might make given the accuracy of Siri.
We really hope to see this as an official Siri feature in the coming updates.
Sireet is available in ModMyi repo for free, go get it.
